My first question would be, do others think your voice is different? You hear your own voice through your skull bone which is quite different from hearing it through the air like when you listen to a recording.

If you mean recording your voice on your phone? There are tricks to make sure you don't go through all the environment processing and echo cancellation. iPhones have VoiceMemo and MusicMemo Apps. VoiceMemo sounds like a cellphone. Near as I can tell, MusicMemo has no processing.
